Module Description

The purpose of this module is to provide the student with the analytical tools to design specific mechanical systems, an awareness of the responsibilities of the mechanical designer, and an introduction to the design process. The student learns through a combination of lectures, tutorials, laboratories, group assignments, formative assessments, and selfdirected learning the skills, knowledge, and professional attitudes, necessary to work with others on the design of mechanical systems. Knowledge (breadth, kind) Breadth: This module applies analytical techniques to the design of mechanical systems. This is achieved by reducing machinery to a series of typical mechanical components and conducting a series of calculations in order to optimise one or more critical variables within the design constraints. (1) (2) (3) (4) (5) (6) (7) (11) (12) (16) The selection of standard components and suitable materials is also part of this module. (8) (9) (10) (11) The design process incorporating legislative, regulatory, ethical and environmental considerations are also covered. (25) (26 (27) (28) Kind: The learner will apply mathematical techniques to solving mechanical problems. (2) (4) (5) (6) (7) (12) (13) (14) (17) (19) The learner will examine and draw conclusions from cases studies. (12) (15) (17) (18) (19) (20) (25) They will also research, write up, and present their findings (21) (22) (23) (24) Know-how and skill (range and selectivity) Range: The learner will develop the mathematical, analytical, research, and decision-making skills needed to solve problems in mechanical design. (1) (3) (6) (7) (12) (14) (15) (17) (19) (20) (22) They will learn to use software tools for calculation, testing solutions through simulation. (29) The student will work in a team on design problems and present solutions. (21) (22) (23) (24) (25) Selectivity: The learner will be able to calculate beam deflection using the Double Integration method and Macaulay's method. (3) They will derive from first principles many of the equations required for mechanical analysis. (1) (2) (3) (7) (12) (20) The student will use empirical formulae to select and evaluate standard mechanical components. (7) (8) (9) (10) (11) (13) Competence (context, role, learning to learn, insight) Context: The learner will apply the knowledge and skills gained to individual and group design exercises within the module and may apply them to group projects during stage three, as well as to their individual project in final stage. (21) Role: The learner has the responsibility to engage ethically with their lecturers, tutors, and fellow learners in developing and applying their learning through completing assignments, preparing for tutorials, sharing group work and fairly crediting its product. (21) (22) (23) (24) Learning to learn: Tutorials, Laboratory work and formative assessment all provide feedback to the learner on their performance, with advice and direction on how to improve if necessary. The research, assignments, and group work also provide opportunities for the learner to learn independent of the lecturer. Insight: The mathematical techniques, design methodologies, and problem solving nature of the module will develop the learner's intellectual capabilities changing their perspective of the natural world. The sense of accomplishment that comes with the mastering of difficult material will also give them the confidence to tackle larger and more complex enterprises. The learner's social skills, including negotiating, asserting, motivating, communicating, and discerning skills can only improve with teamwork.

Module Aims

The aim of this module is to; Equip the learner with the necessary knowledge to research, design, evaluate, and select a range of mechanical components. Enable the learner to gain the personal development and communication skills needed to work with others. Prepare the learner for the career of professional manufacturing engineer.
